But as part of the testimony, Creighton said briefly (before she
was cut off) that 2/3rds of mobile search comes from Apple iOS
devices. That’s pretty interesting considering the share of
Android devices in the market.

Keep this in mind, both regarding Siri as a threat to Google, and with the whole “Android is winning because there are more Android handsets than iPhones” thing.

I’ve speculated for years that by making Apple into an enemy, Google could wind up losing money with Android, long-term, compared to a hypothetical world where they’d kept Android as a BlackBerry-ish OS rather than an iPhone-ish one. iPhone users are the cream of the crop, demographically.
